`TO ALL WHOM I'l MAY CO'lCER-N:

Be it known` that I, ANDREW B. HESTER, ofNorth Vernon, in the county of Jennings, and State of Indiana, have invented a new and useful Improvement on theSash-Balancerfor which a patent was granted to me, dated November 1, 1864, and numbered 44,866; and do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, in Which- Figure 1 is a vieur ot` the window from the room with the sash suspended, the `nord K arranged with this improvement.

Figure 2 is aside view ot' the apparatus C, the pulleys at A and B, and the cord as arranged thereon.

Figure 3 is a top view ofthe plate A, and the three pulleys as arranged thereon.

The object and eil'eet of this improvement are that the cord moves in perpendicular and parallel lines, caus-` ing less friction and greater n eatness of appearance.

The cord is attached to the lever in the apparatus C at ai, thence passes upthrough the plate A at e, thence over the pulley l to the pulley 2, thence down through the plate A atf, and around the pulley 13, thence up through the plate A `at g, then over'the pulley 3, and down again through the plate A at z., and thence down to the apparatus C, and through the clasp therein. l

What I claim as my invention, audfor which Idesire Letters Patent, isr '.lhe` sash-balance, consisting of the plate A, with the pulleys 1 2 3 as arranged thereon, the pulley B, the cord K, the cap C, andthe lever F, the whole constituted and arranged substantially 'as described.

. ANDREW B. HESTER.
